Report of Soils Investigation <br />2215 South Standard Ave., Proposed Addition <br />Santa Ana. California <br />Page 19 of 21 <br />Job No. 40-0613 <br />April 5. 1999 <br />I <br />l <br />shouid srraddle a cut-fill interface. Continuous footings bearing in the well- <br />compacted engineered fill material may be designed using a maximum allowable <br />bearing capacity of 1,800 pounds per square foot. The ailowable bearing pressure <br />may be increased by one third when considering loads of short duration such as <br />wind or seismic forces. <br />A.long the south property line footings of the building on the adjacent lot are <br />parallel to and immediately adjacent to the proposed structure foundations. <br />The bottom of footings @OF) for the proposed structure must match the BOF of <br />the existing structure. Figure 4 shows the approximate dimensions of the existing <br />structure to the south. <br />l0.32Settlernent of Buildins Slab <br />We have analyzed settlement potential anticipated during construction and for <br />long term performance. Construction settlement is expected to occur as loads are <br />applied and structures are brought to their operational weight. Long term <br />settlement is expected to occur over time as a result of compression of wetted or <br />partially saturated soil. Anticipated settlements are related to an applied bearing <br />pressure of 1800 psf and a footing width of approximately I 25 feet. Presented <br />below are tabulated settlement ranges, which can be anticipated within the <br />identified layers. <br />! <br />_l
